Mr Loke Hon Wah, 40, has taken part in all three previous editions of The Straits Times Run.
But so keen was he to sign up again this year that he logged on to his computer and registered at 2pm on Wednesday, the exact moment when entries for the annual mass run opened.
The human resource manager joked: "Even though I (won't be) top in the run, I wanted to try to be No. 1 for the bib number, just for the thrill of it."
He is not the only former par- ticipant who has returned year after year.
Senior IT manager Chan Lai Sui, 52, is another such runner.
In fact, the event has become a yearly family affair for Ms Chan, who signed up for this year's ST Run in the City with her husband and 19-year-old son in the 18.45km category.
She said: "It is a family outing for us. I think the ST Run is a family- oriented run, with distances that are not so intimidating. It encourages more families to sign up."

The run was first held at Punggol Waterway in 2013.
A year later, it moved to the new National Stadium, which reprised its role as host venue last year.
Security officer Paul Chan, 52, who is also a returning participant, said: "I love the ST Run's locations. There is always something new."
This year's event, to be held on May 22, will start and end at the F1 Pit Building.
The route will take participants through iconic city landmarks such as Gardens by the Bay and Marina Bay Sands.
Any runner who has taken part in any of the past editions of the ST Run will enjoy a loyalty discount. •Register at http://www. straitstimesrun.com/
